Book #2: Little Mouse and the Amazing Universe
Outer space is so big and amazing!
Another adventure of a relatable little mouse as he goes to school. The kids receive an interesting school assignment from space. Which planet is the largest or smallest? Which one is the best of all?
Hiiru, Lyly and Antero are working together on a presentation about Mars. Grandpa also wants to help, but his book contains outdated information. What might Mars be like, and how many light-years away is it from Earth? Thinking about this makes Hiiru feel very small, even though the universe is such a fascinating place!
Book #1: Little Mouse’s School Picture Day
The little mouse boy Hiiru, known from the beloved picture books, is ready for grade school where he’ll take on new adventures in illustrated chapter book form! What kind of mischief can happen during a normal school day?
Hiru and his friends are dressed up to get their pictures, and the class photo, taken that afternoon. Will the outfits stay clean until the shoot even though the kids are playing soccer and eating lunch? And what will happen to Hiiru when his head gets stuck in a chair right before the shoot?
This easy-to-read chapter-book series with black-and-white illustrations is cheerful and bursting with gentle humor. Little mouse and his friends will discover that when a problem is big, help is always nearby!
